Met-enkephalin modulates the stress responses of plasma concentrations of corticosterone, delta opioid receptor binding, pro-enkephalin expression, and processing in chickens [PDF]
Frontiers in PhysiologyIntroductionMet-enkephalin is a neuropeptide whose release into the circulation is enhanced by stress. There have been no studies on the effects of peripherally administered Met-enkephalin in chickens.MethodsThe effects of peripheral administration of ...

Effects of Cholinergic and Opioid Antagonists on In Vitro Release of Met-Enkephalin, Somatostatin and Insulin-like Growth Factor-1 by and PENK Expression in Crop, Proventriculus and Duodenum of Newly Hatched Chickens [PDF]
AnimalsThe gastrointestinal (GI) tract is under neural, endocrine and paracrine control. The release (basal and in the presence of either cholinergic and opioid antagonists) of Met-enkephalin, insulin-like growth factor 1 (IGF-1) and somatostatin (SRIF) was ...

Research note: Peripheral administration of Met-enkephalin: Novel attenuation of the adrenal medullary and thyroidal stress responses in young female chickens [PDF]
Poultry ScienceAdrenal hormones play a critical response to stresses in poultry, livestock and other vertebrates. Moreover, there are stress effects on thyroid hormones. Plasma concentrations of epinephrine (EP), norepinephrine (NE), thyroxine (T4) and triiodothyronine

Highly sensitive in vivo detection of dynamic changes in enkephalins following acute stress in mice [PDF]
eLifeEnkephalins are opioid peptides that modulate analgesia, reward, and stress. In vivo detection of enkephalins remains difficult due to transient and low endogenous concentrations and inherent sequence similarity.

THE DISTRIBUTION OF METHIONINE‐ENKEPHALIN AND LEUCINE‐ENKEPHALIN IN THE BRAIN AND PERIPHERAL TISSUES [PDF]
British Journal of Pharmacology, 1977 A method is described for the rapid extraction of opioid peptides from the brain and other tissues. The method is based on acid extraction of tissues followed by adsorption of the extract onto Amberlite XAD‐2 resin. Elution with methanol separates the enkephalins and α‐endorphin from β‐endorphin.Over 90% of the opioid peptide activity isolated from ...

Co‐Expression of Tardive Dyskinesia and Drug‐Induced Parkinsonism in Rats Chronically Treated With Haloperidol [PDF]
Neuropsychopharmacology ReportsAim We aimed to create a rat model of drug‐induced parkinsonism and tardive dyskinesia by chronic administration of haloperidol and examine the expression of direct and indirect pathway markers in the striatum of the model rats.

Role of enkephalin derivative in promoting wound healing and scar remodeling via increased epidermal growth factor in a mouse model [PDF]
Archives of Aesthetic Plastic Surgery, 2023 Background Enkephalin, an endogenous neuropeptide, binds to the delta (δ) opioid receptor and exerts an antinociceptive effect. Recent studies have suggested that neuropeptides might effectuate cutaneous wound healing.
